Hash Generator client-side ?
How to use Hash GeneratorThis tool computes MD5, SHA-1, SHA-256 and SHA-512 hashes from any text. A hash is a fixed-length fingerprint useful for verifying file integrity, comparing two contents or indexing data without storing it in clear text.
All computation happens in your browser through the Web Crypto API and JavaScript. The text you type is never sent to a server, which is essential when you hash confidential data. Note that MD5 and SHA-1 are considered broken for security and should no longer be used to protect passwords.

Frequently asked questions
Can a hash be reversed?
No, a hash function is one-way. You cannot recover the original text from a hash, but you can compare two fingerprints to check that an input is identical.
Is my data sent anywhere?
No. Hashing is computed entirely in your browser. No text is transmitted to a server.
Which algorithm should I choose?
For integrity checks, SHA-256 is a good default. Avoid MD5 and SHA-1 for security since they have known collisions.
Can I hash a password with this tool?
To store passwords, use a dedicated server-side algorithm such as bcrypt or Argon2 with a salt. A plain SHA is not suitable for that purpose.
